US Digital E2 Incremental Optical Kit Encoder (Rotary)

The E2 optical encoder is designed as a direct replacement for the Avago HEDS / HEDM 5500 - 5600 series.

The E2 is a rotary encoder with a molded polycarbonate enclosure, which utilizes either a 5-pin locking or standard connector.This optical incremental encoder is designed to easily mount to and dismount from an existing motor shaft to provide digital feedback information.

The E2 is easy to add to existing applications and only consists of four main components; base, cover, hub/code wheel and optical encoder module.

The E2 is normally designed for applications of 10 feet or less. For longer cable lengths, adding a PC4 / PC5 differential line driver is recommended.

The base and cover are both constructed of rugged 20% glass filled polycarbonate. Attachment of the base to a surface may be accomplished by utilizing one of several machine screw bolt circle options. Positioning of the base to the centerline of a shaft is ensured by use of a centering tool (sold separately). The cover is securely attached to the base with two 4-40 flat head screws to provide a resilient package protecting the internal components.

The internal components consist of a shatterproof mylar disk mounted to a precision machined aluminum hub and an encoder module. The module consists of a highly collimated solid state light source and monolithic phased array sensor, which together provide a system extremely tolerant to mechanical misalignments.

Connection to the E2 product is made through either a 5-pin locking or standard connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.

(1) 60000 rpm is the maximum rpm due to mechanical considerations. The maximum RPM due to the module's maximum frequency response is dependent upon the module’s resolution (CPR). For resolutions of 32 to 1999 CPR the frequency response is 300 kHz, 2000 to 3999 CPR the frequency response is 360 kHz and 4000 CPR and greater the frequency response is 720 kHz

(2) Add 0.125" to the required shaft length when using R-option.

(3) Including Axial play.
